Here is a map for easy access:
The land in which the characters’ adventures take place is known as Rassilon. Other lands were once known to exist, but these have been unreachable for centuries. Rassilon is loosely divided into five main geographic regions. Far to the north is the Hellfrost, a vast expanse of ice and snow, wherein dwell towering frost giants whose skin radiates intense cold, Hellfrost dragons, whose breathe is coldfire, a fire that burns icy cold yet can melt metal, frost vampires, victims of the intense cold who feed on the warmth of the living, and Hellfrost mammoths, whose breath can freeze a man’s blood in his veins. The permanent ice and snow radiates, so legends say, from a colossal spike of blue ice at the Hellfrost’s center. Surrounding this is the outer Hellfrost, a realm caught in perpetual winter. Hardy souls struggle to survive against the elements, frost giant raiders, orc tribes, and frostreavers, men driven mad by the Hellfrost wind, which howls across the plains and through the taiga forests. Surrounding the outer reaches of the Hellfrost is the Icewall, a mile high barrier of solid ice. Many expeditions have been launched over the Icewall, but few have returned. Those who survived reported seeing only endless tracts of snow and ice.
Next are the High Winterlands, a wild and dangerous realm where the temperature rarely rises near freezing point. As one travels south, so the snow and ice grow less, and one enters the Low Winterlands. Here life is hard, but bearable, though the temperature remains bitterly cold. The southernmost region is called the Hearthlands. The mountains, swamps, forests, and plains have succumbed to the eternal cold, yet there is still hope. These are the most settled lands, though food grows scarcer each year and constant attacks by fell beasts drain valuable resources.
